DISINFECTING APPARATUS.

Specification of Letters Patent.

Patented Aug. 6, 1907.

Application filed August 4,1906. Serial No. 329,261.

To all whom it may concern:

Be it known that I, WILLIAM J. BOWERMAN, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Disinfecting Apparatus, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to apparatus designed for disinfecting closets, urinals, and the like, and consists in the novel and peculiar construction of the mechanism, and in the arrangement and combination of its parts.

In the drawing illustrating the apparatus, the figure is a vertical central section therethrough.

For the purpose of illustrating the construction and operation of the mechanism, I have shown the same in connection with the ordinary form of low-down flushing tank, the tank proper or reservoir being indicated by the reference-letter A, and having, as is customary, a removable top B, an inlet pipe 0, and a discharge or waste pipe D, both projecting upwardly within the tank, and the waste pipe terminating in a flaring end, forming a valve-seat D.

The mechanism controlling the waste pipe may be of ordinary construction, consisting of a valve E, seating at D, an operating stem G therefor, a weight H for holding the valve normally to its seat, traveling in a guide casing I, which in turn is adjustably secured upon an overflow pipe J communicating with the waste pipe below the valve. L is the usual operating cord for the flushing valve, connected to the stem G through the medium of a pivoted link M, and a projection M extending from the link through and beyond the casing in the usual manner.

The valve mechanism for the inlet is particularly designed for the disinfecting apparatus and is of the following construction,O represents the valve casing supported upon the upper end of the inlet pipe 0, provided with a removable cap a at its upper end, and a plurality of vertical apertures b, and preferably a series of lateral openings 0 at its lower end. (1 represents the valve seat, and P the valve controlling the inlet, having a hollow plunger head Q working in the upper portion of the casing, as shown. B represents an operating member for the valve in the form ofa finger, pivoted between ears or lugs e on the exterior of the valve casing and extending through slots or openings f g in the casing and head respectively within said head, and adapted upon its operation to actuate the plunger, and, consequently, the valve. T designates a float of the usual construction, connected to the valve-operating member by a stem U.

V represents the disinfectant holder in the form preferably of a casting, having an inlet passage h and outlet i of considerably larger magnitude than the inlet, and a passage j connecting the inlet and outlet and forming a bypass therebetween. A fill opening 70 is formed in the upper portion of the holder, which is closed by an apertured threaded plug Z, in which is inserted the lower end of a magazine W, extending upwardly from the reservoir beyond the normal level of water, and in a position where the disinfectant, which may be in the form of pellets, can be conveniently introduced in the apparatus.

m represents a cap closing the upper end of the magazine.

The lower end of the inlet valve casing is provided with a conduit 0, with which the holder V has communication, by means of a suitable supply connection 10, while the opposite end of the holder communicates, through a suitable conduit q, preferably with the waste pipe within the reservoir or tank 011 the discharge side of the flushing valve. 1 8 represent suitable screens arranged over the inlet and outlet of the holder, which serve to prevent the disinfecting material from being washed out.

In operation, the holder and its magazine'i's filled with the disinfecting material, the supply being sulficient to disinfect the closet or urinal for a considerable period of time. Upon the operation of the flushing valve E, the tank contents is discharged and the reservoir refilled by the water supply passing through the inlet. It will be noticed that the said inlet is divided, one branch, formed by the apertures in the bottom of the valve casing, leading to the tank proper, While the other branch is connected to the disinfectant holder. Thus, as the tank is being refilled, a part of the supply passes through the disinfecting material, and is discharged directly into the bowl or other device to be disinfected. The apertures in the valve casing conmagnitude than the conduit leading to the holder, so that the tank is filled in the ordinary manner and the supply shut off by the closing of the inlet valve. It will be noticed, however, that, as the holder discharges independently of the tank, the flow of water will continue through the holder and into the bowl after the flushing valve has reseated, whereby an after-flow is provided, completely filling the device that it discharges into. The supply from the branch leading to the holder also passes through the by-pass .I, which serves primarily as an additional means for the overflow referred to. I

It will be apparent from the construction of the mechanism as thus set forth that merely a portion of the water supply enters the disinfectant holder, so that the disinfecting material will not be dissolved in too great quantity and thus wasted.

I have shown herein the valve mechanism for the inlet as located at a point below the normal level of stituting the tank branch, are of sufliciently greater water in the tank. This position is not at all essential, but in such cases I have providedmeans whereby the tank contents will not enter the disinfectant holder, so that after the tank has been flushed no water will pass through the material. The means employed for this purpose consists of a valve X, connected to and operating with the main inlet valve P, the former valve being of the plunger type and working within a tubular extension Y, formed on the valve casing for that purpose. Attention is further directed to the fact that the arrangement of the valves at the inlet is such that the closure for the disinfectant holder operates prior to the main inlet valve. This is for the purpose of preventing any flow of Water through the holder after the tank has become partially filled. The result is that only a slight amount of water passes through the holder, which becomes strongly saturated with the disinfectant, and in this condition passes directly to the bowl or other device. Thus, a maximum strength of the disinfectant is obtained.

What I claim as my invention is,

1. In disinfecting apparatus, the combination with a reservoir provided with a divided valve-controlled inlet and a valve-controlled outlet, of a disinfectant holder having communication with one of the branches of the inlet, and a discharge conduit for said holder leading outside the reservoir.

2. In disinfecting apparatus, the combination with a reservoir provided with an inlet and an outlet, of independent valves controlling the inlet and outlet, a disinfectant holder having a discharge port and a supply connection with the reservoir inlet, and an automatically-operating closure controlling the flow through said supply connection.

3. In disinfecting apparatus, the combination with a reservoir provided with a valve controlled inlet and outlet, of a disinfectant holder having a discharge port and a supply connection with the reservoir inlet, and an automrit'icallybperati'ng closure for said supply connection controlled in its operation by the inlet valve.

4. In disinfecting apparatus, the combination with a reservoir having a divided valve-controlled inlet and a branches, and a discharge conduit leading from said holder I to and having communication with the waste pipe on the discharge side of its valve. I

G. In disinfecting apparatus, the combination with a reservoir provided with a valve-controlled outlet, of a water supply conduit adapted to discharge within the reservoir, a valve controlling the discharge through said conduit, a disinfectant holder, a conduit establishing communication between the holder and the water supply conduit on the discharge side of its valve, and a discharge conduit for the holder leading outside the reservoir.

7. In disinfecting apparatus, the combination of a reser voir provided with a valve-controlled inlet and outlet, and a disinfectant holder having an inlet port in communication with the reservoir inlet, a discharge conduit leading outside the reservoir, and a by-pass between said conduit and inlet.

8. In disinfectingapparatus, the combination with a reservoir, provided with a valvecontrolled inlet and out let, of a disinfectant holder having'a discharge port and a supply connection with the reservoir inlet, and an automatically-operating valve for the supply connection, adapted to close the said connection prior to the seating of the main inlet valve.

In testimony whereof I aflix my signature in presence of two witnesses.
